wififund_less3_exer1 build issue

[cfs]

I was working through the wifi course in dev academy. I'm having a hard time getting exercise 1 to build. Anyone else running into this? I'm building for nrf7002dk_nrf5340_cpuapp.

Hello Collin,

Could you check if you are having any issues building other default samples in NCS?

I just tried a lesson 2 sample that built without issue. And then a lesson 4 solution failed. I guess this may be on my end.

[Elfving]

Could you try a creating a default peripheral sample to see if that works?

Simply press "create a new application, pick one of the suggested samples and try building it for a suggested and supported board.

  

If that fails I think there is something wrong with the installation of the SDK or toolchain. Or maybe you've selected a toolchain that doesn't correspond to the SDK.

Regards,

Elfving

I am able to create new projects by copying samples. It seems to be just the course exercises. I'm using sdk and toolchain v2.5.2

A colleague tried to build this application as well and got the same output as above.
